FIELD OF THE INVENTION

The present invention relates generally to surgical methods and apparatus and, more specifically, to systems and methods of treating pelvic conditions, such as urinary or fecal incontinence and female vaginal prolapse conditions, including enterocele, rectocele or posterior prolapse.

BACKGROUND OF THE INVENTION

Pelvic health for men and women is a medical area of increasing importance, at least in part due to an aging population. Examples of common pelvic ailments include incontinence (e.g., fecal and urinary), pelvic tissue prolapse (e.g., female vaginal prolapse), and conditions of the pelvic floor via a transperitoneal procedure.

Urinary incontinence can further be classified as including different types, such as stress urinary incontinence (SUI), urge urinary incontinence, mixed urinary incontinence, among others. Other pelvic floor disorders include cystocele, rectocele, enterocele, and prolapse such as anal, uterine and vaginal vault prolapse. A cystocele is a hernia of the bladder, usually into the vagina and introitus. Posterior prolapse, or rectocele, can occur when the fascia that separates the rectum and the vagina weakens or tears, thereby causing a bulge of the vaginal wall. Pelvic disorders such as these can result from weakness or damage to normal pelvic support systems.

Urinary incontinence can be characterized by the loss or diminution in the ability to maintain the urethral sphincter closed as the bladder fills with urine. Male or female stress urinary incontinence (SUI) generally occurs when the patient is physically stressed.

Urinary incontinence can be characterized by the loss or diminution in the ability to maintain the urethral sphincter closed as the bladder fills with urine. Male or female stress urinary incontinence (SUI) occurs when the patient is physically stressed.

A variety of treatment options are currently available to treat incontinence. Some of these treatment options include external devices, behavioral therapy (such as biofeedback, electrical stimulation, or Kegal exercises), injectable materials, prosthetic devices and/or surgery. Depending on age, medical condition, and personal preference, surgical procedures can be used to completely restore continence. Types of procedure found to be an especially successful treatment option for SUI in both men and women can include sling or implant procedures. There are a variety of different sling procedures. Slings used for pubovaginal procedures differ in the type of material and anchoring methods.

One such implant procedure is the Elevate® anterior or posterior implant systems sold by American Medical Systems, Inc. of Minnetonka, Minn. The Elevate® posterior implant system utilizes self-fixating tips that allow for mesh placement in the sacrospinous ligament through a single vaginal incision to treat apical and/or posterior vaginal prolapse.

There is a desire to provide a system for repairing apical support and posterior vaginal wall support based on sound anatomic concepts and long term outcome advantages.

SUMMARY OF THE INVENTION

The present invention provides prolapse repair system and procedure for treating incontinence and prolapse by repairing vaginal apical support and posterior vaginal wall support. The system can include one or more anchor devices and one or more extending members, such as a suture. The system can further include a mesh or like support or suspension structure provided intermediate the one or more anchor devices and the one or more extending members.

To facilitate the repairs, anchoring can be directed to the coccygeous sacrospinous ligament or complex, or other like anatomical structures, via a transperitoneal (through the peritoneum) approach, wherein the one or more anchor devices are engaged directly into the target ligament or tissue complex. The one or more extending suture members can be constructed of an absorbable, or continuous delayed absorbable, material. With such a transperitoneal approach, improved bilateral suspension can be achieved with less deviation of the vaginal axis resulting.

A vaginal retractor can be employed to keep the small bowel from dropping into the field, as well as to provide adequate lighting and displacement of the sigmoid colon. The retractor can include an inflation member or device (e.g., via fluid inflation internal or external to the retractor) that upon intraperitoneal insertion can occupy the upper pelvis to lift the intestinal contents out of the pelvis.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring generally to FIGS. 1-12, a prolapse repair system 10 and methods are shown. Various embodiments of the system 10 can include anchor support devices 12 having one or more anchors 14 and one or more members 16 extending from the one or more anchors 14. The one or more anchors can include angled tines 15 to promote engagement and fixation within tissue of the patient. The one or more members 16 can be a suture member. The suture members 16 can be constructed of a material adapted to absorb into the body over time (e.g., continuous delayed absorption). In certain embodiments, the one or more members 16 can include two or more suture members extending from the anchor, as shown in FIGS. 2 and 4. The anchor 14 can be constructed of a polymer or like material. The system 10 provides a device and procedure that can position the vaginal apex so that it is not distorted, or at least reduces any distortion.

Various embodiments of the anchor support device 12 can include a mesh portion or member 18 provided intermediate the anchor 14 and the one or member 16 s, as shown in FIGS. 3-4. As such, the mesh member 18 can support or reinforce tissue upon deployment. The mesh member 18 can be constructed of polymer filament materials, or can be molded or otherwise formed into a generally planar structure or from a thin generally planar film or sheet material. Examples of acceptable polymer materials available in constructing or forming portions of the anchor device 12 and its components can include polypropylene, polyethylene, fluoropolymers, metals or like materials. The various implants or systems, anchors, mesh, tools, devices, features and methods disclosed in U.S. Patent Application Publication No. 2011/0112357 are envisioned, in whole or in part, for use with embodiments of the present invention. Accordingly, the above-identified publication is fully incorporated herein by reference in its entirety.

The anchor support device 12 can be deployed and provided to repair vaginal apical support and posterior vaginal wall support via a transperitoneal (through the peritoneum P) approach. Namely, the physician can access the coccygeous muscle-sacrospinous ligament complex (C-SSL complex), or the sacrospinous ligament, via a transperitoneal access approach TPA (e.g., FIG. 6, via small peritoneum P window or opening(s)) and insert one or more of the anchors 14 directly into the target ligament, on each side of the patient, with the suture members 16 extending from the anchors 14 to serve as suspension members to the vaginal wall. A transperitoneal access approach allows for easy bilateral suspension with less deviation of the vaginal axis and provides an advantageous route for the procedure.

A needle device 20, as shown in FIG. 12, can be included with the system 10 to deploy and fixate the anchors 14 at the target site. The needle device 20 can include a handle portion 22 and a needle portion 24. The needle portion 24 can be straight or curved and a distal tip 26 is adapted to selectively engage and disengage with the anchors 14. The tip of the anchors 14 and/or the distal 26 of the needle device 20 can facilitate passing the anchors 14 and the attached members 14 through (e.g., pushing through) a tissue pathway, tissue, and eventually the target tissue site. One or more actuators or like mechanisms can be included to facilitate the release or disengagement of the anchor 14 from the distal tip 26.

Once the anchors 14 are engaged with the target tissue site, the suspension sutures 16 are brought out through the full thickness of the posterior vaginal wall (e.g., including the peritoneum P), as demonstrated in FIG. 7-9. As depicted in FIG. 7, two anchors 14 can be fixated in the target ligament site on each side of the patient, thereby providing four suspension sutures 16 extending through the posterior vaginal wall on each side (e.g., total of eight). Other embodiments can use a single anchor 14 on each side, or three or more anchors on each side, depending on the repair needs and the anatomical structure of the patient. The suspension sutures 16 can be tied together (e.g., to another adjacent suture) for tensioning, thereby recreating level 3 support and facilitating posterior wall support and correction of the high rectocele (FIG. 9). In other embodiments, the anchor 14 can be passed with the suture members 16 directly into the upper portion of the uterosacral ligament in lieu of or in addition to another target site such as the C-SSL complex.

It can be a challenge to obtain adequate exposure to all safe passages of the anchors 14 and sutures 16 in the respective ligaments (uterosacral or sacrospinous) with a intraperitoneal suspension as is disclosed herein. However, a vaginal retractor 30 can be employed (e.g., through the vagina V) to keep the small bowel from dropping into the field, as well as to provide adequate lighting and displacement of the sigmoid colon, as demonstrated in FIG. 10. The retractor 30 can include an inflation member or device 32 (e.g., via fluid (gas or liquid) inflation internal or external to the retractor 30) that upon intraperitoneal insertion can occupy the upper pelvis to lift the intestinal contents out of the pelvis. As shown in FIG. 11, the end of the retractor 30 including the device 32 can include firm but generally flexible extensions 34 provided and positioned on the retractor 30 to prevent bowel from slipping down around the balloon device 32 during use. The long, generally flat retractor 30 can include an illumination device 36 to promote visualization in the field during deployment and use.
